And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment. 1 Jn 3:23
How can we be commanded to believe something? This seems irrational and illogical. How can you be commanded to believe something if you happen to be inclined not to believe? If someone where to come up to you and say, “Fairies are real. You have to believe this, or you’re going to hell,” you would consider this person an irrational idiot. However, this passage in the book of 1 John is telling us that God commands us to believe. Is God irrational and illogical? Certainly not!
So how can we understand this?
This is actually fairly easy to understand. The reason God commands us to believe is because…
# 1, the truth is painfully obvious to anyone who will take the time to seek it out genuinely, and…
# 2, the real reason many people do not believe is not because they genuinely don’t think God is real, but don’t like what God has to say and so disbelief is the easiest way to excuse themselves from God’s instructions.
The bible says that the minds of the unbelievers have been blinded by the god of this world (i.e. Satan) so that should not believe the truth (2 Co 4:3-4). Their own sin has allowed the devil to put a dark cloud over them that prevents them from seeing truth. God says that creation itself is sufficient evidence of His existence. God also says that He puts the knowledge of Himself in every person (Rom 1:19-21).
A command from God to believe is perfectly logical. He is saying, in essence, “Throw aside your sin and selfish desires, and accept the truth that has been plainly revealed.”
